Are civil and military explosives the same? In other words, are we using the same explosives in mining and warfare? Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid-1800’s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil engineering application. The Industrial Revolution carried new discoveries in explosives and initiation technologies. A specialization principle, therefore, operates between military and civil application of explosives thanks to new products economics, versatility, strength, precision or capability to be stored for long periods of time without significant deterioration. https://www.thebalance.com The following factors shall be considered to determine the blast area: • Geology or material to be blasted, • Blast pattern, • Burden, depth, diameter, and angle of the holes, • Blasting experience of the mine, • Delay systems, powder factor, and pounds per delay, • Type and amount of explosive material, and • Type and amount of stemming. #blasting #mining #industry #coal

NOTE: Although this video shows an up-close look at the blasting process, NEVER go near an active surface mine or blast site without Federal training and permission. FYI, the white bags are Emulsified Ammonium Nitrate. The read cap is TNT and the silver rod that is connected to it by the yellow wire is the blasting cap, it's what ignites the shot. The white pebbles that are emptied into the blast holes by the powder trucks are the main explosive- "ANFO" or Ammonium Nitrate, which is a mixture of fertilizer and diesel fuel. Once the holes are filled with explosives, rock fines or "stemming" is pushed back in the holes and packed down to keep the explosives under pressure. After all the holes are loaded and rigged up, it's time for the fireworks! And remember kids, don't try this at home! Want to see more Blasting?

We often think of nuclear bombs as extreme weapons of destruction. While they are certainly that, in the 1960s the world's superpowers began investigating more practical uses for these powerful devices. The US and the Soviet Union were embattled in the heat of the Cold War in the early 1960s. Both countries had stockpiled nuclear weapons, but thousands of them simply sat idly across their respective country. The US subsequently created operation plowshare and the Soviet Union a program named "Nuclear Explosions for the National Economy". Operation Plowshare in the US was formed to explore the possibility of using nuclear explosions for excavation or natural gas fracturing. The evidence of this project's test can still be seen through craters in the Nevada desert. Surprisingly this research project persisted for nearly 20 years, from 1958 to 1975. The Soviets were also researching practical uses of nuclear explosions, and like the US, their research was focused on natural gas and mining. Unlike the US, however, little concern was given to the environmental impact of these Soviet nuclear tests. Soviet engineers behind the project once contaminated a densely populated region along the river Volga. They also decided to blow up a river to create a reservoir – which they succeeded in doing – except it's still radioactive to this day. During this nuclear research, scientists realized that they might be able to solve a problem that had been raging on for years.

Wide of police vehicle and police outside crime scene STORYLINE: South African police said on Friday they had found nearly 3 tons (2.49 metric tons) of commercial explosives in a house in southern Johannesburg. Gauteng Provincial Police Commissioner Perumal Naidoo told Associated Press Television News that an 18-year-old woman and a 22-year-old man, both of Zimbabwean nationality, had been arrested during Friday's raid. He added that officers were acting on a tip-off. Police think the explosives had been stolen from a shipping container depot and would be used by a criminal syndicate to blow up cash machines. The find may alarm some people in view of the forthcoming World Cup that starts in June, but Naidoo was quick to point out that the explosives were destined for use in robberies, and were typical of the kind used in recent attacks on ATM machines, in which criminals blow up the machines to get the money out. "We assure you the World Cup will be safe. And there's no doubt about it," he said. South Africa imports large quantities of explosives for its mining industry, and the explosives were of the type used in mine exploration. The find caused consternation among local school pupils who assumed the explosives would be used to kill people and disrupt the World Cup.

We visited the miners market which is a bunch of shops selling everything the miner’s heart longs for. Apart from the usual like pickaxes, helmets, torches and the lot you can also freely buy dynamite. Sticks of dynamite for sale in a Potosi market. The explosives are used by the local miners who work in the cooperative mines of Cerro Rico. So everyone and everything can buy it from a small kid to a miner to a very excited tourist. A complete set of a stick of dynamite, the detonator, a fuse and some other chemical which makes for a bigger bang cost you USD 2. We didn't do any dynamite action afterward. I am against this idea due to putting us at risk of getting an injury or seeing nature being damaged by unnecessary items. Guide felt the same way, which was a good thing!

Another combat proven munition for the US military and us air force the CBU 105 has served the US Air Force very well. The CBU-97 Sensor Fuzed Weapon is a United States Air Force 1,000-pound (450 kg)-class non-guided (freefall) Cluster Bomb Unit (CBU). It was developed and produced by Textron Defense Systems. The CBU-97 in conjunction with the Wind Corrected Munitions Dispenser guidance tail kit, which converts it to a precision-guided weapon, is designated CBU-105. Overview The CBU-97 consists of an SUU-66/B tactical munition dispenser that contains 10 BLU-108 submunitions. Each submunition contains four hockey-puck-shaped sensor-fused projectiles called Skeets. These detect target vehicles, such as tanks, armored personnel carriers, trucks and other support vehicles, and fire a kinetic energy penetrator downwards at them. Operation The 40 Skeets scan an area of 1,500 by 500 feet (460 m × 150 m) using infrared and laser sensors, seeking targets by pattern-matching. When a Skeet finds a target it fires an explosively-formed penetrator to destroy it. If a Skeet fails to find a target, it self-destructs 50 feet (15 m) above the ground; if this fails, a back-up timer disables the Skeet. These features are intended to avoid later civilian casualties from unexploded munitions, and result in an unexploded-ordnance rate of less than 1%. As the CBU-97 approaches its designated aim-point, the dispenser skin is severed into three panels by an explosive cutting charge. The slipstream peels away these panels, exposing the 10 BLU-108 submunitions. An airbag ejects the forward five submunitions, then five in the aft bay. Following a preset timeline, the submunitions deploy parachutes so that they are spaced about 100 feet (30 m) apart. Then each submunition releases its chute, fires a rocket motor that stops its descent and spins it on its longitudinal axis, and releases Skeets 90 degrees apart, in pairs. Each spinning Skeet makes a coning motion that allows it to scan a circular area on the ground. The laser sensor detects changes in apparent terrain height such as the contour of a vehicle. At the same time, infrared sensors detect heat signatures, such as those emitted by the engine of a vehicle. When the combination of height contours and heat signatures indicative of a target are detected, the Skeet detonates, firing an explosively formed penetrator (EFP), a kinetic energy penetrator, down into the target at high speed, sufficient to penetrate armor plating and destroy what is protected by it. Even well-armored vehicles such as main battle tanks, while having massive armor protection on the front and sides, are only lightly armored above, and relatively easily penetrated. Each bomb can spread penetrators over an area of 15 acres (61,000 square metres) or more. According to an ABC News consultant, an attack by this bomb would basically stop an armored convoy moving down a road. While the bomb was designed during the Cold War for fighter-bombers flying at low altitude below radar cover to attack Soviet tanks, a single B-52 high altitude heavy bomber can destroy an entire armored division with these bombs, where in the past dozens of aircraft would have had to drop hundreds of bombs for the same effect. The CBU-97, or CBU-105 version, is deployed by tactical aircraft from altitudes of 200 to 20,000 feet (60 to 6,100 m) Above Ground Level (AGL) at speeds of 250 to 650 knots (460 to 1,200 km/h). The weapon was first deployed, but not used, during Operation Allied Force when NATO entered the Kosovo War. Sensor-fused weapons were first fired in combat during the 2003 invasion of Iraq. In 2010 the US government announced the sale to India of 512 CBU-105 Sensor Fuzed Weapons. The expected platform is the SEPECAT Jaguar. Saudi Arabia has also requested the CBU-105. Operators In addition to the United States, the CBU-105 has been ordered by India, Oman, Saudi Arabia, South Korea, Turkey, and the United Arab Emirates.

This film from the United States Bureau of Mines presents general descriptions of the hazards of radon daughters in uranium mines, and outlines the environmental control, principles and procedures for mitigating the hazard. Scenes of underground mines show the origin and reason of the hazard, and various methods of ventilation are shown on how to correct the condition. Uranium mining occurred mostly in the southwestern United States and drew many Native Americans and others into work in the mines and mills. Despite a long and well-developed understanding, based on the European experience earlier in the century, that uranium mining led to high rates of lung cancer, few protections were provided by employers or government for US miners before 1962 and their adoption after that time was slow and incomplete. Some US officials and scientists advocated ventilation requirements in US mines as a proactive, preventative measure during the 1950s, on the basis of their knowledge of European experience. Duncan Holaday, an industrial hygienist with the PHS, has generally been recognized as the most prominent advocate for ventilation. He led the effort to obtain measurements of radon in the mines, and he used the data to argue forcefully within the government that ventilation would be effective and was feasible. His arguments achieved only limited success, as there was government resistance to requiring ventilation and his views were not made public at the time. The Atomic Energy Commission (AEC) was an obstacle. In the late 1940s, controversy erupted in the New York Operations Office over the hazards from beryllium and uranium mining. The AEC wrote worker health requirements in contracts with companies that handled beryllium. After conflicting recommendations from staff, it chose not to establish such requirements for uranium. It claimed to lack legal authority, but it did not explain the legal difference between uranium and beryllium. The AEC did not lack knowledge: records of a January 25, 1951, internal meeting of AEC and PHS staff reveal that, on the basis of early measurements, they believed that radon was present in levels that would cause cancer and that ventilation could abate the hazard. Public acknowledgment of this problem was apparently squelched. For instance, Hueper, the scientist who wrote the 1942 review and who was then at the National Cancer Institute, was forbidden to speak in public about his concerns about the health hazard of radon in uranium mines. It is reported that he was even forbidden to travel west of the Mississippi, lest he say too much to the wrong people. The resulting high rates of illness among miners led in 1990 to passage of the Radiation Exposure Compensation Act. For more details, see the outstanding article, The History of Uranium Mining and the Navajo People, in the Sept 2002 American Journal of Public Health at http://www.ajph.org/cgi/reprint/92/9/1410 .

Mine Safety and Health Administration Timbering in Underground Anthracite Mines (Part 2) DVD589 (Was VC807) - 1994 Timbering is the most common roof support method used in underground anthracite mines. The system of timbering is governed by the character of the top and bottom, thickness of the coal vein, pitch of the coal vein, life of the entry, haulage system, and the operator's approved roof control plan. This videotape demonstrates the fundamentals and characteristics used in installing typical timber sets: single prop, post and bar (two-piece sets), and "double timber" (three-piece sets).

The Mining Foundation of the Southwest is pleased to recognize Eben Robinson, Area Manager, Arizona and New Mexico, Southwestern Energy, as a 2017 recipient of the Medal of Merit Under 40 for induction into the American Mining Hall of Fame. Born in Kingman and raised in Wickenburg, Eben Robinson wanted to design cars from concept to production. At Wickenburg High School he enjoyed wood shop, football and wrestling, graduating as Salutatorian and earning a scholarship to study Mechanical Engineering at The University of Arizona. Confronted with the reality that his scholarship would not extend for a second year and his education might be halted, Robinson reached out to friends he had made in the UA Mining Department and was awarded a Phelps Dodge scholarship to study Mining Engineering and ventured into an unexpected new vocation. In 2001 Robinson joined IMC Potash (later Mosaic) in Carlsbad, NM, where he worked in all aspects of underground engineering, served on the Mine Rescue Team, ran continuous improvement programs, oversaw a core drilling campaign, supervised a 16-man production crew, and chaired the Potash Section of the Society of Mining, Metallurgy and Exploration (SME) In 2005, Robinson returned to Arizona for Phelps Dodge (later Freeport-McMoRan) as Senior Engineer in the Mine Technology Group. He left in the copper crash of 2008 as Program Manager, working on innovation projects in haulage and mass material transport in the US, Chile, and Peru. Following a stint as Maintenance Manager at Marco Crane and Rigging, Robinson joined Southwest Energy LLC in 2010 as Technical Services Engineer. He was soon promoted to Innovation Manager, working to improve safety and efficiency in commercial explosives used in mining. Robinson is now Area Manager in Arizona and New Mexico, where he looks after mining accounts for Southwest Energy, as well as forecasting and logistics for Apache Nitrogen. Viewing responsible resource extraction as the most basic means of defeating poverty and improving living standards globally, Robinson once chaired the Tucson Chapter of SME for three years consecutively and has served as Treasurer, Vice President and President of the Mining Foundation of the Southwest. He is currently a member of the Industry Leadership Board of the Mining Department at The University of Arizona. Robinson was a recipient of the Outstanding Senior Award in Mining Engineering at the UA, the SME Outstanding Young Professional Award and the SME Program Area Manager Award.

While walking through the territory of a factory, located in the industrial area of the city, I noticed a weird concrete block with a metal gate on the side of it. I opened it and a ladder climb later I was in a dark, small tunnel leading to an underground bomb shelter/safe house.

Here at this location, the locals are still using a Stamp Mill to process Rock Ore that contains Gold particles. The first type of a stamp mills date back to 300 A.D. in China when water-driven trip hammers were used to crush of ore rocks. Around 900 A.D., dry stamp mills driven by manual power were used to make iron. The same technology was in use to some degree by the 12th century, to liberate materials from ore through gravity concentration. Early dry stamp mills were used for grinding components used to make black powder used in explosive and functioned very similarly to a mechanized mortar and pestle. By the 1500s the economics allowed for the increase and demand for metals—particularly silver and copper. This called for a new type of machine that could grind at a higher capacity than any manually-operated machine at the time was capable of. The use of water and wind power already used in mills for grinding flour was applied to the crushing of minerals. Sadly, there are still alot of stamp mills in use in Africa. They are very outdated and I hope to change this with our efforts to modernize the equipment used for gold processing.

William Mills, a hand grenade designer from Sunderland, patented, developed and manufactured the "Mills bomb" at the Mills Munition Factory in Birmingham, England, in 1915. The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland. Roland and Mills were later engaged in a patent lawsuit. The Mills bomb was adopted by the British Army as its standard hand grenade in 1915, and designated as the No. 5.

Buying gold as an investment -- good or bad? There is a huge portion of financial media that fixates on gold. The most common argument you’ll see is that gold is a hedge for economic collapse – gold is seen as a safe place to store money because it’s been used as a form of currency for thousands of years. That history, plus gold’s global appeal and limited supply sells a lot of people on the value of gold as an investment. But is it actually a good idea? As an investor, you’re looking to buy something that will be worth more in the future than it is today. To measure that, a lot of people will look at the “intrinsic value” – or the inherent worth of a company, property, or asset. Most of this analysis will look at the money the potential investment over time might generate In the case of a company, you’d look at the expected profits the business would generate over time. As a shareholder, you’re a part owner of the business and so your stock entitles you to a sliver of those earnings. For a business that is growing over time, earnings should go up, and the value of your piece of ownership should follow. What’s tricky about gold is that as an asset, it doesn’t actually generate cash. The piece of gold you own today will be the same piece of gold 5 years from now, no more and no less. If you buy a house, you can decide to rent it out, and over time the rental payments you receive could provide a steady flow of cash. Alternatively, you can live in the house and instead of paying rent month after month, you would be making mortgage payments and building equity over time in an asset that is capable of creating cash flows. On its own, gold can’t generate cash, which makes it harder to value. The value of gold is really tied to its scarcity – that gives it value in the jewelry market and it makes it useful as a store of value and means of exchange. Some of you probably heard that and thought “what the heck does that mean?” Globally, gold is recognized as a precious metal, and that worldwide recognition means it readily can be exchanged across borders and cultures, which is part of the reason why major institutions like central banks maintain gold reserves. It’s also why some investors want in on gold. They view it as a hedge against economic instability and inflation. Paper dollars, like the US dollar are “fiat currency” -- meaning they have value because we say they have value -- sound familiar? So, if events unfold that lead people to question the value of a fiat currency, OR the government takes actions that change the value of a currency -- like printing waaaaay more bills and giving them out to people -- the currency can lose value. If a currency loses value, the relative value of gold, as expressed in that currency, will shoot up, allowing investors in gold to profit. Some people keep money in gold because it is less tied to any one government and isn’t as impacted by inflation or an economic collapse in any one country. But it’s merit as an investment really depends on the timeline you’re looking at. From September 2008 to August of 2011, the price of gold went up over 100% while stocks in the US eeked out 1% gains on a total return basis. There’s money to be made investing in gold, but it comes down to being right about gold at the right time -- because gold tends to surge in value when major financial systems are struggling. Since September of 2011, stocks have returned over 180% on a total return basis while the price of gold has fallen nearly 30% AND the returns of the S&P 500 trounce those of gold on a 1,3,5, and 10 year basis. And for people with a very long time horizon, since 1990, The S&P 500 has posted 1,400% gains on a total return basis. Over the same nearly 30 year period, gold has returned 220%. If you are worried about an economic downturn, it may make sense to have a small portion of your portfolio in gold, but it certainly shouldn’t be your main investing strategy, and for many time periods, you’d be better off being all in stocks. ------------------------------------------------------------------------ Subscribe to The Motley Fool's YouTube Channel: http://www.youtube.com/TheMotleyFool Join our Facebook community: https://www.facebook.com/themotleyfool Follow The Motley Fool on Twitter: https://twitter.com/themotleyfool

Nuclear technology is constantly in the news. So how exactly do you make nuclear fuel? Special thanks to Life Noggin for animating this video! Check them out: http://www.youtube.com/lifenoggin Read More: Fuel Cycle Facilities http://www.nrc.gov/materials/fuel-cycle-fac.html “The U.S. Nuclear Regulatory Commission (NRC) regulates uranium recovery facilities that mill uranium; fuel cycle facilities that convert, enrich, and fabricate it into fuel for use in nuclear reactors, and deconversion facilities that process the depleted uranium hexafluoride for disposal.” Uranium processing http://www.britannica.com/EBchecked/topic/619232/uranium-processing “Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.” About Nuclear Fuel Cycle https://infcis.iaea.org/NFCIS/About.cshtml “Nuclear Fuel Cycle can be defined as the set of processes to make use of nuclear materials and to return it to normal state. It starts with the mining of unused nuclear materials from the nature and ends with the safe disposal of used nuclear material in the nature.” Nuclear Fuel Processes http://www.nei.org/Knowledge-Center/Nuclear-Fuel-Processes “Nuclear power plants do not burn any fuel. Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission.” ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

RUBBER BLASTING MATS WHAT ARE RUBBER BLASTING MATS? Massive rubber/canvas mats woven from disused conveyor belts, using various techniques to fix the weft and warps together. WHAT THEY DO: Blasting mats are designed to stop rock fly when using high explosives. The high density of the rubber provides mass to absorb the energy of flying rocks. WHY ADROMEDA BLASTING MATS ARE USED? Being made from disused materials with minimum embodied (recycling) energy, they provide good value and durability under normal conditions. DELIVERY AVAILABLE AUSTRALIA WIDE & INTERNATIONALLY For more information please contact - +612 6760 3773 (Australia) or visit our website www.rubberbeltmats.com.au. We Look Forward To Hearing From You! ------------------------------------------------------------------------------------------------------------------------------- BLASTING MAT TESTIMONIAL FROM: STONECO | QUARRIES SCONE NSW 2337 | 4th September 2012 Re: Andromeda Blasting Mats We have used Andromeda Blasting Mats in our civil and Quarry work and found them strong, durable and very effective. The weave pattern allows conforming to uneven ground while allowing the gasses to escape but retain the rock fly. They are easily lifted and placed into position with strong 13mm slings either end. The mats are a cheap form of insurance when you are blasting in built up or sensitive areas. I would recommend their use when blasting.

Despite irrefutable scientific evidence calling out the dangers of asbestos, 2 million tons of the carcinogen are exported every year to the developing world, where it's often handled with little to no regulation. For this episode of VICE Reports, correspondent Milène Larsson traveled to the world's largest asbestos mine in the eponymous town of Asbest, Russia, to meet workers whose livelihoods revolve entirely around the dangerous mineral. Surprisingly, the risks associated with asbestos mining didn't seem to worry the inhabitants; in fact, asbestos is the city's pride, celebrated with monuments, songs, and even its own museum. Larsson then visits Libby, Montana, another mining town almost on the other side of the globe, where the effects of asbestos exposure are undeniable: 400 townspeople have died from asbestos-related diseases, and many more are slowly choking to death. Why is the deadly industry of mining and selling asbestos still alive and well?
